Monoclonal human IgG1 (N298A) antibody against E. coli β-galactosidase

Anti-β-Gal-hIgG1 (N298A) features the constant region of the human IgG1 (N298A) isotype and the variable region of Mouse IgG2a Control. Mouse IgG2a Control is a mouse IgG2a monoclonal antibody that targets E. coli β-galactosidase (β-Gal).

This antibody was generated by DNA immunization with a plasmid expressing the β-Gal gene in Swiss mice.

Anti-β-Gal-hIgG1 (N298A) can be used as an isotype control for human IgG1 antibodies containing the N298A mutation. Antibodies with this mutation contain a modified Fc region designed to limit antibody-dependent cytotoxicity (ADCC) and complement-dependent cytotoxicity (CDC) [1, 2], as this mutation eliminates their ability to bind to human Fcγ receptors.

Anti-β-Gal-hIgG1 (N298A) was generated by recombinant DNA technology. It has been produced in Chinese hamster ovary (CHO) cells and purified by affinity  chromatography with protein G.
